I have Raspberry Pi5 with a 512GB Raspberry Pi NVMe M.2 HAT+ module.
I can successfully boot into Raspberry Pi, but when I attempt to set up Home Assistant SELECT YOUR STORAGE DEVICE is empty when “Exclude system drives” is checked. I had the same problem when I attempt this process using the SSD that came preloaded with the Pi5.
Yes, I have a single NVMe drive. I am trying to get Home Assistant up and running. However, when I run rpi-imager, in the SETUP, I select Raspberry Pi 5 → in the choose OS, I select OTHER SPECIFIC-PURPOSE OS → HOME AUTOMATION → HOME ASSISTANT → HOME ASSISTANT OS 18.1 (RPI 5), but the SELECT YOUR STORAGE DEVICE is empty and the EXCLUDE SYSTEM DRIVES is checked.
If I uncheck the system drives, I see ORIGIN:RPI-SWAP 2GB
Are you running rpi-imager from the RPI5? If so, that’s wrong.
A workaround would be to install an os on a SD card, then boot the RPI from the SD card and then run rpi-imager. Then you’ll be able to install haos on the SSD.
